I have decided to buy a spartan from cobbs diesel with an s&b intake and the Dp back exhaust but i was wondering that some people have been mentioning stuff about job 3 trucks. I bought my truck in June or July of 2007 but i am worried that if i buy the spartan i am going to have problems. Can someone please explain to me what this is and can you tell me what my truck is?
Thanks, Abel

It has not been a problem for me. My build date is 1/07 it was the first 6.4 that came to the dealer. I've been spartan tuned for 38,000 of the 68,000 miles on my truck. I would suggest if you are going to do a lot of racing to get the TCM.

I am not going to be doing a lot of racing unless a dodge or chevy is next to me. All im looking for is an increase in mpg's.

You wont have any problems with your truck running the spartan as long as you don't load the performance 210 tune. I have a job 1 truck and loaded that tune yesterday and it shut my truck down. Called spartan and Mick told me how to correct it. They are still working on a fix for it. As far as mileage I hear mixed reviews, but I can say from experience that I have seen a significant increase in my mileage and very happy with the spartan. Transmission seems to shift a little rough at times but thats it. I have a stock truck with 3.73 gears, s&b intake and dpf/cat delete spartan 250 tuned. Lots of great dealers out there, but I have to put my plug in for Aaron @ dpfdelete. Awesome guy to deal with and will always return your call.

How do you upgrade your TCM? I thought the normal tuner would do this for you???

Spartan offers a TCM which works better than stock...especially the job 1 TCM.

LFD132 what do you mean the tranny shifts rough? It's supposed to shift firmer, (kinda hard) but it's better for your tranny in the long run. Mine shifts kinda hard while just poking around town, but when you give it the throttle it seems to smooth out alot.

I thought the 210 tune was a heavy towing tune? What tune is best for me, i drive it really only on the weekends and rarely on the weekdays, i live on a dusty, 2 mile dirt road, and all i want is fuel economy. I am going to drop in a s&b intake and an afe dp back exhaust but now the spartan is starting to scare me. Am i safe to use the 250 tune on my truck?
